' rotated7 and one of the hand tion, fthe lock nuts l() are tightened toindicate particular' time desired, for instance," the time at which thetrain on which the apparatus is located is dus at a certain station, thenaine oi" which latter is displayed by the station, indicator.

The use oi our improved indicator is as iol lows: Assuming that theappliance is positioned in the cab of a locomotive, and that theengineer has orders to neet a regularl train at a certain ste tion, theloclr nuts l0 are loosened to allow the shafts 8 to be freely wheels 9is now engaged and manipulated so as to roll the sheet i3 from one shaft8 to the other until the naine of the station designated as a meetingpoint is brought into a position immediately in front of the opening 6,which is covered by the section of red glass. The slides 21 are insertedin the grooves oi the kee ers behind the sections of green and white gass, thus covering said sections, and light 'from the larnp 225 thrownforward bv the i'eiiector 4 through the section of red glass 19 and inturn ap `ears through the perforations forming theetters of the naineor' the station designated, and also through the openings 15 adjacentthe name of the station. Aiter the sheet 13 has been shifted to .theproper posli]- the shaits Segainst any rotation, thus pre venting'anyshiting oi the sheet 13 due to vibration of the locomotive or earupon which the appliance is carried. Thus 'the appliance is set for use,and the engineer or driver oi the locomotive or car is constantlyreminded ol the particular station Where a regular train is to loe met4By shifting the slides 21, the Section of green or White glass maybecxposed, as desired, to indicate special and freight trains and, ifdesired, a greater number of openings, such as 6, may be one ployed tomeet various conditions.

An appliance of our improved construction 1s simple., inexpensive,easily adjusted and set for use, serves as a constant reminder as to thedesignated meeting points for trains, and the like, and, when properlyused greatly reduces the liability oi accidents resulting fromdisregarding orders and instructions.

i. ln a device of the class described, a housing, partition arrangedtherein, in which partition is formed a series oi openin sections oicolored'glass arranged 1mIneiately to the rear of said openings, aperforated sheet arranged for operation so as to pass in front of all ofthe o enings in the partition, a lamp arranged in tie housing to therear of the partition, and non-transparent lates ar` ranged to slide inthe housing imme iately to- Qthe rear of the sections of colored glass.v
